| 摘 要： | 现代军用直升机经常执行特殊飞行任务，其机载电子设备具有功率大、瞬间振荡、高热通量等特点，使得环控系统的冷却需求呈指数上升趋势，进而制约着直升机的巡航功能和战斗性能的提升。针对直升机机载大功率电子设备的冷却需求，结合制冷剂、冷却液循环等子系统，搭建地面稳态试验台，针对蒸发器、冷凝器等关键部件进行了地面稳态试验。研究过程采用仿真与试验相结合的方法，开展了制冷循环中蒸发器、冷凝器等关键部件稳态仿真计算，且完成了蒸发器、冷凝器的换热性能试验研究，对所建立的仿真模型进行了有效性校核与参数修正。上述研究可为后续直升机液冷/蒸发制冷系统的关键部件设计提供一定的参考。

| Abstract: | At present, the cooling requirement of the high-powered, time-vary and large heat flux airborne avionics on military helicopters is increasing exponentially. In order to improve the performance of military helicopters and solve the cooling requirement of avionics, a new type of liquid cooling system, consisted of a liquid cooling loop and a vapor loop subsystem is developed. Steady state experiments with evaporator and condenser have been carried out on ground. The method of combining simulation with experiment is adopted in research process. The steady-state simulation calculation and experimental performance of evaporator and condenser are carried out in refrigeration cycle. The simulation model is validated and the parameters are revised. The above research can provide some references for the design of key components of helicopter liquid-cooling/evaporative refrigeration system. |
